The Pololu Adjustable 9-30V Step-up/Step-Down Voltage Regulator S18V20AHV is a versatile device designed to manage input voltages ranging from 3 V to 30 V, adjusting them to produce a stable output between 9 V and 30 V. This regulator employs a single-ended primary-inductor converter (SEPIC) topology, ensuring efficient power conversion with typical efficiencies between 80% and 90%. It is particularly suitable for battery-powered applications where the input voltage may fluctuate above or below the desired output voltage as the battery discharges.

This regulator is part of the S18V20x family, which includes both adjustable and fixed-output versions. The adjustable nature of this model allows for flexibility in various applications, making it ideal for scenarios where precise voltage control is necessary. The device is equipped with several protective features, including reverse-voltage protection, over-current protection, thermal shutdown, and an under-voltage lockout, ensuring reliable operation under various conditions.

The regulator's compact design includes four mounting holes for secure installation and offers multiple connection options through smaller holes for header pins and larger ones for terminal blocks. The ENABLE pin allows the board to enter a low-power state, reducing quiescent current significantly. Adjusting the output voltage is straightforward, requiring only a multimeter and a light load, with the potentiometer allowing fine-tuning of the voltage output.

Note: Ensure input voltage remains within specified limits to prevent damage to the regulator.
